Introduction

In this tutorial, I will be showing you how to add a weapon that freezes other props, it's quite basic but the main reason is to show you how to freeze entities with LUA as Player:Freeze().

Setting up the files

Addon

Create a new file called shared.lua inside YourAddon/lua/Weapons/swep_freeze

Gamemode

Create a new file called shared.lua inside YourGamemode/entites/weapons/swep_freeze

Coding it

The point of this tutorial is not to show you how to add a weapon, the code I will describe will be mostly the freeze code.

 
 
if SERVER then --Is this running on the server
	AddCSLuaFile("shared.lua") --Send this file to the client for usage
end
 
if CLIENT then --Is this running on the client
	SWEP.PrintName = "Pay Day Baton" --Name
	SWEP.Slot = 1
	SWEP.SlotPos = 3
	SWEP.DrawAmmo = false --Draw ammo in bottom right corner
	SWEP.DrawCrosshair = false --Draw crosshair?
end
 
SWEP.Author = "KillerLUA" --Author
SWEP.Instructions = "Left/Right click to freeze" --How to use
SWEP.Contact = "" --Contact
SWEP.Purpose = "Freezes Props" --Purpose
 
SWEP.ViewModelFOV = 62 --View Model Positioning
SWEP.ViewModelFlip = false --Ignore this :D
SWEP.AnimPrefix = "stunstick" --Preset animation info, ignore this too
 
SWEP.Spawnable = false --Not spawnable by non-admin players
SWEP.AdminSpawnable = true --Only spawnable by admins!
 
SWEP.NextStrike = 0
 
SWEP.ViewModel = Model("models/weapons/v_stunstick.mdl") --The model while being held
SWEP.WorldModel = Model("models/weapons/w_stunbaton.mdl") --World model (on the ground)
 
SWEP.Sound = Sound("weapons/stunstick/stunstick_swing1.wav") --The sound
 
SWEP.Primary.ClipSize = -1
SWEP.Primary.DefaultClip = 0
SWEP.Primary.Automatic = false --Automatic weapon?
SWEP.Primary.Ammo = ""
 
SWEP.Secondary.ClipSize = -1
SWEP.Secondary.DefaultClip = 0
SWEP.Secondary.Automatic = false
SWEP.Secondary.Ammo = ""
 
function SWEP:Initialize() --When the SWEP is first seen by the client/server
	if SERVER then self:SetWeaponHoldType("normal") end --Set the hold type
end
 
function SWEP:PrimaryAttack() --When you left click (by default)
	if CurTime() < self.NextStrike then return end
 
	if SERVER then
		self:SetWeaponHoldType("melee")
		timer.Simple(0.3, function(wep) if wep:IsValid() then wep:SetWeaponHoldType("normal") end end, self) --Checks that the swep hasn't quickly been switched
	end
	self.Owner:SetAnimation(PLAYER_ATTACK1)
	self.Weapon:EmitSound(self.Sound) ---Emit a sound, the stunstick wack
	self.Weapon:SendWeaponAnim(ACT_VM_HITCENTER)
 
	self.NextStrike = CurTime() + .4
 
 

We need to be the server to do this so make sure we are!

 
	if CLIENT then return end --No clients past here
 

If what we're looking at isn't valid then do nothing!

 
	if not ValidEntity(self.Owner:GetEyeTrace().Entity) then return end
 

First, we get the owner of the weapon, then what they are looking at. We set the move info to none (Frozen).

 
	self.Owner:GetEyeTrace().Entity:SetMoveType(MOVETYPE_NONE)
 

Back to the rest of the code

 
end
 
function SWEP:SecondaryAttack() --When you right click (by default)
	self:PrimaryAttack() --Run Primary Attack
end
 
 

In this script we create the stunstick animation and run payday on our victim.
